My 2 year old has all his favourite films and programmes on Sky+ so any help would be appreciated. Seems as if the hard drive keeps locking and the box eminates a constant hum - as if the disc is stuck spinning. If I turn off from the mains and restart it works for an hour or so and then locks up again. 2 questions... 1. Is there something I can do to fix this and 2. if I have to replace the box, has anyone devised a clever way of keeping what's been saved by transferring it to the new box?
